2026-01-14drm/amd/display: Initialise backlight level values from hwVivek Das Mohapatra
Internal backlight levels are initialised from ACPI but the values are sometimes out of sync with the levels in effect until there has been a read from hardware (eg triggered by reading from sysfs). This means that the first drm_commit can cause the levels to be set to a different value than the actual starting one, which results in a sudden change in brightness. This path shows the problem (when the values are out of sync): amdgpu_dm_atomic_commit_tail() -> amdgpu_dm_commit_streams() -> amdgpu_dm_backlight_set_level(..., dm->brightness[n]) This patch calls the backlight ops get_brightness explicitly at the end of backlight registration to make sure dm->brightness[n] is in sync with the actual hardware levels.

2026-01-14drm/amdgpu/userq: Fix fence reference leak on queue teardown v2Srinivasan Shanmugam
The user mode queue keeps a pointer to the most recent fence in userq->last_fence. This pointer holds an extra dma_fence reference. When the queue is destroyed, we free the fence driver and its xarray, but we forgot to drop the last_fence reference. Because of the missing dma_fence_put(), the last fence object can stay alive when the driver unloads. This leaves an allocated object in the amdgpu_userq_fence slab cache and triggers This is visible during driver unload as: BUG amdgpu_userq_fence: Objects remaining on __kmem_cache_shutdown() kmem_cache_destroy amdgpu_userq_fence: Slab cache still has objects Call Trace: kmem_cache_destroy amdgpu_userq_fence_slab_fini amdgpu_exit __do_sys_delete_module Fix this by putting userq->last_fence and clearing the pointer during amdgpu_userq_fence_driver_free().

2026-01-14drm/amdkfd: Fix GART PTE for non-4K pagesize in svm_migrate_gart_map()Donet Tom
In svm_migrate_gart_map(), while migrating GART mapping, the number of bytes copied for the GART table only accounts for CPU pages. On non-4K systems, each CPU page can contain multiple GPU pages, and the GART requires one 8-byte PTE per GPU page. As a result, an incorrect size was passed to the DMA, causing only a partial update of the GART table. Fix this function to work correctly on non-4K page-size systems by accounting for the number of GPU pages per CPU page when calculating the number of bytes to be copied.

2026-01-14drm/amdkfd: Fix SVM map/unmap address conversion for non-4k page sizesDonet Tom
SVM range size is tracked using the system page size. The range start and end are aligned to system page-sized PFNs, so the total SVM range size equals the total number of pages in the SVM range multiplied by the system page size. The SVM range map/unmap functions pass these system page-sized PFN numbers to amdgpu_vm_update_range(), which expects PFNs based on the GPU page size (4K). On non-4K page systems, this mismatch causes only part of the SVM range to be mapped in the GPU page table, while the rest remains unmapped. If the GPU accesses an unmapped address within the same range, it results in a GPU page fault. To fix this, the required conversion has been added in both svm_range_map_to_gpu() and svm_range_unmap_from_gpu(), ensuring that all pages in the SVM range are correctly mapped on non-4K systems.

2026-01-14drm/amdkfd: Relax size checking during queue buffer getDonet Tom
HW-supported EOP buffer sizes are 4K and 32K. On systems that do not use 4K pages, the minimum buffer object (BO) allocation size is PAGE_SIZE (for example, 64K). During queue buffer acquisition, the driver currently checks the allocated BO size against the supported EOP buffer size. Since the allocated BO is larger than the expected size, this check fails, preventing queue creation. Relax the strict size validation and allow PAGE_SIZE-sized BOs to be used. Only the required 4K region of the buffer will be used as the EOP buffer and avoids queue creation failures on non-4K page systems.

2026-01-14PCI/P2PDMA: Reset page reference count when page mapping failsAlistair Popple
When mapping a p2pdma page the page reference count is initialised to 1 prior to calling vm_insert_page(). This is to avoid vm_insert_page() warning if the page refcount is zero. Prior to setting the page count there is a check to ensure the page is currently free (ie. has a zero reference count). However vm_insert_page() can fail. In this case the pages are freed back to the genalloc pool, but that does not reset the page refcount. So a future allocation of the same page will see the elevated page refcount from the previous set_page_count() call triggering the VM_WARN_ON_ONCE_PAGE checking that the page is free. Fix this by resetting the page refcount to zero using set_page_count(). Note that put_page() is not used because that would result in freeing the page twice due to implicitly calling p2pdma_folio_free().

2026-01-14PCI: Remove useless WARN_ON() from devresPhilipp Stanner
PCI's devres implementation contains a WARN_ON() which served to inform users relying on the legacy devres iomap table that this table does not support multiple mappings per BAR. The WARN_ON() can be regarded as useless by now, since mapping a BAR multiple times is legal behavior and old users of pcim_iomap_table(), the accessor function for that table, did not break in the past PCI devres cleanup. New PCI users will hopefully notice that pcim_iomap_table() is deprecated and are unlikely to use it for mapping the same BAR multiple times. Moreover, WARN_ON()s create noisy, difficult to read error messages which can be more confusing than helpful, since they don't inform the user about what precisely the problem is.

2026-01-14ACPI: processor: idle: Add debug log for states with invalid entry methodsHuisong Li
According to ACPI spec, entry method in LPI sub-package must be a buffer or an integer. The driver will disable the state whose the entry method is invalid by zeroing flags in struct acpi_lpi_state. The entry method is very key in cpuidle. A debug log is very useful for developers.

In pcie_ptm_create_debugfs(), if devm_kasprintf() fails after successfully allocating ptm_debugfs with kzalloc(), the function returns without freeing the allocated memory, resulting in a memory leak.

2026-01-14ACPI: processor: Fix NULL-pointer dereference in acpi_processor_errata_piix4()Tuo Li
In acpi_processor_errata_piix4(), the pointer dev is first assigned an IDE device and then reassigned an ISA device: dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB, ...); dev = pci_get_subsys(..., PCI_DEVICE_ID_INTEL_82371AB_0, ...); If the first lookup succeeds but the second fails, dev becomes NULL. This leads to a potential null-pointer dereference when dev_dbg() is called: if (errata.piix4.bmisx) dev_dbg(&dev->dev, ...); To prevent this, use two temporary pointers and retrieve each device independently, avoiding overwriting dev with a possible NULL value.

2026-01-14i3c: master: Introduce optional Runtime PM supportAdrian Hunter
Master drivers currently manage Runtime PM individually, but all require runtime resume for bus operations. This can be centralized in common code. Add optional Runtime PM support to ensure the parent device is runtime resumed before bus operations and auto-suspended afterward. Notably, do not call ->bus_cleanup() if runtime resume fails. Master drivers that opt-in to core runtime PM support must take that into account. Also provide an option to allow IBIs and hot-joins while runtime suspended.
